Title: Improvement in preparation of carbon sulfo selenide
IPC: C01B31/26
Filed: 1939-02-16
Abstract: 526,743. Carbon sulphoselenide. WING- FOOT CORPORATION. Feb. 16, 1939, No. 5091. Convention date, June 24, 1938. [Class 2 (iii)] Carbon sulphoselenide (C S Se) is prepared by reacting hydrogen selenide with an aryl isothiocyanate or an aryl thiourea. In the latter modification it is preferable that the aryl thiourea should, before the addition of the hydrogen selenide, be treated with a non- oxidizing mineral acid such as dilute sulphuric acid to generate the aryl isothiocyanate in the reaction mixture. Alternatively, the mineral acid may be dispensed with and the hydrogen selenide passed directly into molten aryl thiourea. The reaction temperature when an aryl thiocyanate or an acid treated aryl thiourea is approximately room temperature. In an example, a toluene solution of phenyl mustard oil is treated with hydrogen selenide at room temperature until no more gas is adsorbed. The mixture is then distilled, and the fraction which passes over between 75-100C. contains the desired carbon sulphoselenide. Alternative solvents to toluene which are mentioned include xylene and high boiling naphtha. Alternative starting materials to phenyl isothiocyanate mentioned include tolyl-, xylyl-, alpha-naphthylbeta-naphthyl, and substituted aryl-isothiocyanates.

Title: Improvements in or connected with telephone systems
IPC: H04Q5/16
Filed: 1942-04-17
Abstract: 554,772. Party line systems. NORRIS, W. H. April 17, 1942, No. 5143. [Class 40 (iv)] In a party line system, each substation has a selector with a normal contact and a circuit making contact in a particular position depending on the number of impulses required to set the selector at the substation, all the selectors with the exception of that at a calling substation being operated by impulses and the calling and speaking circuits being completed over the normal contact at the calling station and the other contact at the desired substation. All selectors restore when a connection is released. Construction of selector.-The contacts are carried by a fixed plate 15 and the wiper 3a by a spindle 3 on which is mounted a ratchet wheel 4 and a loose disc 7 having teeth 7a on its periphery engageable by an arm 10a operated by the magnet armature and face teeth 7b in engagement with a spring pawl 8a on an arm 8 fixed to the spindle. The armature 2, 5 pivoted at 2a carries a pin 11 engaging a spring for operating the arm 10a and a pawl 6a for stepping the ratchet wheel 4. The pawl is biased to the position shown by the weight of arm 6b, an adjustable stop 13 and a fixed guide 12 being provided. Impulses step the ratchet wheel and hold the disc 7, arm 8 being moved over the face teeth 7b. If the impulses are slow, a spiral spring 9 on spindle 3 rotates it back to normal when the magnet releases, disc 7 being rotated by pawl 8a, but in the case of impulses of normal speed, the inertia of disc 7 prevents this and the spindle is rotated forward step-bystep. During conversation, the magnet is maintained operated. In the circuit arrangement, Fig. 5, substation A has called substation B but B has not yet replied. When A lifts his receiver, the impulse transmitter 18 and telephone instruments (line 24, 24a) and local battery 25 are connected in series over normal contact 16 to the line and magnet 1 is operated to hold his selector and cause engaged lamp 21 to light. Line relays 22 at B and other stations pulls up and responds to impulses and at station B the selector completes the calling circuit over contact 17 and the local battery 25, the calling device 20 being operated by a sluggish relay 20a to prevent operation when contact 17 is passed on a call to another substation. When B lifts his receiver, the selector magnet is held in a local circuit and the engaged lamp lit, the magnets at substations not in conversation being held over the line so that these substations cannot connect up. To prevent the possibility of restoration of a selector at a called station at the moment when the receiver is lifted the selector may be locked by a mechanical link connected to the receiver. In a modification, Fig. 7 (not shown), a threewire line and central battery are provided, the line relays being omitted and the magnets directly operated.
